IPC: C01B33/154
Filed: 1989-05-26
Abstract: PURPOSE:To obtain the subject substance having improved purity by adding a chelating agent to an aqueous solution of an alkali silicate, adding the solution to a mineral acid solution containing H2O2 and subjecting the formed silica gel to washing with acid, dehydration, drying and calcination. CONSTITUTION:A chelating agent is added to an aqueous solution of an alkali silicate having an SiO2 concentration of <=10wt.% and the solution is heated at >=100<= to adjust the viscosity to 10 to 1,000 poise. The obtained aqueous solution of silicate is poured into a mineral acid solution containing H2O2 and having an acid concentration of >=2 normal for several seconds to several minutes and the mixture is stirred to gelatinize the silica from the aqueous solution of alkali silicate and, at the same time, to transfer the alkali metal, metallic impurities and radioactive impurities into the mineral acid. The obtained gelatinous silica is washed with warm water at >=40%, thrown into an acid solution containing the chelating agent and H2O2 and having an acid concentration of >=0.5 normal, washed with the acid by stirring at >=40 deg.C for <=30min, dehydrated and dried at 100 to 400 deg.C to obtain a porous silica having an average particle diameter of 1,000 to 2,000mum and a BET specific surface area of 800 to 1,000m<2>/g. The porous silica is calcined at 500 to 1300 deg.C, crushed and sieved.

IPC: G06T1/00
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To efficiently convert full-color images to the monochromatic images of a desired color by one operation or easy operations close to it. SOLUTION: An optional color is selectively specified from the respective kinds of the colors decided beforehand from an input part 4. Then, a CPU 1 scans the respective pixels of the full-color images, calculates luminance from the RGB value, accesses a mono-color conversion table 8-5 corresponding to the specified color and retrieves the mono-color conversion table 8-5 by the calculated luminance. Thus, when the luminance is converted to the RGB value of the specified color, the CPU 1 replaces the RGB value of the full-color images to the RGB of the specified color.

Abstract: PURPOSE: To increase the speed of TIG welding and improve the quality of welded joints by directing the TIG arc forward along the welding advance direction thereby sufficiently preheating unwelded base metals in a DC TIG welding method.  
     CONSTITUTION: In the DC TIG welding method, a filler 6 is on the side backward of the welding advance direction W and while it is being supplied in the arrow Y direction, its end is held dipped in molten pool 7. Here, the welding base metal 1 is made positive pole and a non-consumable electrode 2 negative pole. With respect to the current to be flowed to the filler 6, the filler 6 is made positive pole and the base metal 1 negative pole. Hence, mutually repelling magnetic fields generate around the electrode 2 and filler 6 and the arc 3 having flexibility deflects so as to go apart from the filler 6, thereby preheating the base metal 1 and increasing the welding speed. At this time, the current of the electrode 2 is made 500A or less and the current of the filler 6 200A or less. Magnetic fields are changed by flowing pulsation to the filler 6 and weaving of the arc 3 is accomplished by the change thereof.
